自定义Junit运行器不会忽略Assume.assumeTrue（someFalseCondition）的测试

Question

我编写了一个自定义Junit运行程序来控制如何运行参数化测试。以下是它的源代码。

问题是现在从它扩展的类不支持Assume.assumeTrue（someFalseCondition）。它不会被忽略，而是会失败，例如

org.junit.internal.AssumptionViolatedException: got: <false>, expected: is <true>
    at org.junit.Assume.assumeThat(Assume.java:70)
    at org.junit.Assume.assumeTrue(Assume.java:39)
    at org.terracotta.tests.base.AbstractTestBase.setUp(AbstractTestBase.java:68)

    at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50)
    at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193)

下面这节课中我有什么遗漏。

public class TcTestRunner extends Suite {
  /**
   * Annotation for a method which provides parameters to be injected into the test class constructor by

  private class TestClassRunnerForParameters extends BlockJUnit4ClassRunner {

    private final List<TestConfig> fParameterList;

    TestClassRunnerForParameters(Class<?> type, List<TestConfig> parameterList, int i) throws InitializationError {
      super(type);
      fParameterList = parameterList;
      fParameterSetNumber = i;
    }

    @Override
    public Object createTest() throws Exception {
      return getTestClass().getOnlyConstructor().newInstance(computeParams());
    }

    private TestConfig computeParams() throws Exception {
      try {
        return fParameterList.get(fParameterSetNumber);
      } catch (ClassCastException e) {
        throw new Exception(String.format("%s.%s() must return a Collection of arrays.", getTestClass().getName(),
                                          getParametersMethod(getTestClass()).getName()));
      }
    }

    @Override
    protected String getName() {
      return String.format(fParameterList.get(fParameterSetNumber).getConfigName());
    }

    @Override
    protected String testName(final FrameworkMethod method) {
      return String.format("%s[%s]", method.getName(),     fParameterList.get(fParameterSetNumber).getConfigName());
    }

    @Override
    protected void validateConstructor(List<Throwable> errors) {
      validateOnlyOneConstructor(errors);
    }

    @Override
    protected Statement classBlock(RunNotifier notifier) {
      return childrenInvoker(notifier);
    }
  }

  private final ArrayList<Runner> runners = new ArrayList<Runner>();

  /**
   * Only called reflectively. Do not use programmatically.
   */
  public TcTestRunner(Class<?> klass) throws Throwable {
    super(klass, Collections.<Runner> emptyList());
    List<TestConfig> parametersList = getParametersList(getTestClass());
    for (int i = 0; i < parametersList.size(); i++)
      runners.add(new TestClassRunnerForParameters(getTestClass().getJavaClass(), parametersList, i));
  }

  @Override
  protected List<Runner> getChildren() {
    return runners;
  }

  @SuppressWarnings("unchecked")
  private List<TestConfig> getParametersList(TestClass klass) throws Throwable {
    return (List<TestConfig>) getParametersMethod(klass).invokeExplosively(null);
  }

  private FrameworkMethod getParametersMethod(TestClass testClass) throws Exception {
    List<FrameworkMethod> methods = testClass.getAnnotatedMethods(Configs.class);
    for (FrameworkMethod each : methods) {
      int modifiers = each.getMethod().getModifiers();
      if (Modifier.isStatic(modifiers) && Modifier.isPublic(modifiers)) return each;
    }

    throw new Exception("No public static parameters method on class " + testClass.getName());
  }

}
